The present invention has relation to molds for casting printers furniturevor clumps, more particularly the elongated skeleton strips utilized by printers as spacing media,

=- the present invention having for its object toprovide for the particularly expeditious and efiicient manufacture of such strip.

According to the present invention we provide a two-part mold, one part of which is slidable in relationtothe other or comple= mentary part, said two-part mold incorporating in combination a plurality of protruding matrices on the one part adapted to cooperate with a longitudinal channel in the other or complementary'part, means for filling the interior of the mold with the fluid casting metal, and mechanical means for slidably displacing one part in relation to the other for removing the skeleton strip. The

one part of the mold may incorporate a plurality of channels of differing transverse dimensions and the other or complementary part a corresponding plurality of matrices co-operable with the said channels, and, further, a closure member may be adapted for through which the channels are fed and the trunnions which co-operate with the operating lever.

Where a plurality of channels are utilized as shown, these have, a differing transverse measurement -or section. The base is provided withan inwardlydirected flange b to "constitute a channel 721 (see particularly FigureB wherein a closureplate 0 (Figure. 2) is adapted to slide; Clamps a l are adapted to hold the closure plateat that extremity remote from the flange 6. 05 is a handle providedupon the closure. plate, Provided on the under face of the closure plate a are a plurality of spaced matrices 0.1 (see Figure 5 adapted to ,cooperate with the channel or channels al in the base-a, Each matrix, may be of subinvolving four slightly convergent walls or faices'as shown andthe bases of the matrices are adapted to slide along the-bases of the channels. The closure plate 0 is provided with a depending flange 6'2 adaptedto close 5 the extremities of the channels a1=the remote extremities being closed by the fixed bar a2 (Figuref one, two or more hoppers 03- according to the number of channels 'areprovid'edth'rough which the molten metal may.

home. trunnions 04 on its upper face with which be passed when the closure plate is fully The closure plate a is provided with the limbs of a U-shaped operating handle a3 pivoted to the base a are adapted to cooperate.

Figure 9 illustrates a frame or stand device al for supporting the mold at an inclination. f In this respect it will be notedthat the hoppers 03 are designed for such incli. nation, and when the molten metal is poured into the mold the filling thereof is assisted by the gravitation of the metal along the channels. Such a supporting frame however is not indispensible inasmuch as the mold if desired may be used in a horizontal position and the hoppers 03 appropriately adapted for'receiving the molten metal whilst.

the mold is in such a position. Figure 12 illustratesa closure member 6 adapted to be applied to one of the matrices '01 for the purpose of closing off a section of the channel. In this manner any predetermined length of the skeleton frame f illustrated in Figure 11 may beobtained.

In operation the closure plate 0 with its one or more series of matrices is slid home in relation to the base plate a by means of its handle 05 and the clamps a l afterwards tightened. The flange 02 closes the extremities of the channels a1 and these said channels are effectively closed superficially by the plate 0 which engages the flange member b, The molten metal is poured into the channel, or

the desired channel if a plurality are present,

by way of the hopper or hoppersc3, and the metal allowed to gravitate or flow along the channel or channels between the matrices to constitute the skeleton strip illustrated in Figure 11 used by the printer as spacing media. The metal havingset, the clamps aft are released and the handlemember operated to displace the closure platejby means of the cam parts a5 engaging the trunnions 04 bringing the skeleton strip now constituted away from the channels and leaving it in position upon the protruding matrices from which it can be readily removed by hand or with the i aid of a simple tool. When a length of skeleton strip .is required short of the overall length of the channel the closure member 1 e is applied to one of the matrices in the manner shownin Figures 7 and 8.- This closure me1n-' ber exactly fits the matrix in the channel and thereby limits the effective length of'the said channel eration.

'A' mold com'prising'abase plate having a channel opening through the top and the front end thereof and closed at its rear end, a closure plate adapted to be superimposed upon said base .plate to close the upper side of said channel, means carried by said closure plate for cooperation with the base plate to close the front end of said channel, means forming a guideway carried by the base plate to receive marginal portions of the closure plate to hold the latter operatively superimposed upon the base plate, trunnions projecting laterally from the closure plate, and a lever elementpivoted to the base plate for cooperation with said trunnions to slide th closure plate into said guidewav. 7
